CVE-2026-45310Public exploitNetwork attack vector

Internal service disclosure via unchecked redirect targets

Published May 28, 2026 · Updated May 28, 2026

SSRF in CodeWhale before 0.8.22 allows remote attackers to read data from internal services through a redirected fetch_url request. The fetch_url tool checks only the initial hostname's resolved address, while reqwest follows as many as five redirects without applying is_restricted_ip to each target. Exploitation requires prompt injection in processed files or web content that induces the model to call the tool, exposing cloud metadata or credentials when reachable.
